How to calculate the Speed Of Electron

Answer 1

Answer:

$<font color= "blue">$Hey mate answer of your question is given below by me....

Explanation:

The speed of electrons

The mass of the electron is m = 9 × 10 -31 kg.

The electronic charge is e = 1.6 × 10 -19 C.

For an electron gun with a voltage between its cathode and anode of V = 100V the electron will have a speed of about v = 6 × 10 6 m/s. (Relativistic effects have not been taken into account.)

I hope it can help you..

Answer 2

Answer:

The electron starts from rest (near enough) so the kinetic energy gained is given by ½mv 2 where m is its mass and v is its speed.

So we can say that: ½mv 2 = eV

The mass of the electron is m = 9 × 10-31 kg

The electronic charge is e = 1.6 × 10-19 C

For an electron gun with a voltage between its cathode and anode of V = 100V the electron will have a speed of about v = 6 × 106 m/s. (Relativistic effects have not been taken into account.)
